Process if installing is very tedius but I have compiled all the steps that can be used to install sublime in your linux system.
The Key method was not working for me so I tried other method and in the end I want the signature "subl" in sublime text to use directly in my termial.
So here you go!
Download tarball as per 64 or 32 bit from here-
https://www.sublimetext.com/3
Go to download folder and extract zip
tar vxjf sublime_text_3_build_3211_x64.tar.bz2
Move extracted binaries to opt
sudo mv sublime_text_3 /opt/
sudo ln -s /opt/sublime_text_3/sublime_text /usr/bin/sublime
Test if its working
sublime
Optional - if you want to have subl alias to open sublime then
open bashrc
sublime ~./bashrc
Add this line in the end
alias subl=sublime
Source bashrc to update changes
source ~/.bashrc
Test now it should work
subl
Done
